The Station Operations Review Committee has reviewed and concurs with these evaluations.

SUMMARY

A. Design Change Packages 2EC-3268 Pkgs 1&2 "Installation Of Manway And Davit For No. 21 CCHX" -

DCP 2EC-3268 entails the installation of an 18" diameter manway and davit on the turnaround side

{front) closure head for No. 21 CCHX. In addition, the entire head (wetted side only) will be reclad with a 3/8" thick 90-10 Copper Nickel liner. A new turnaround end closure head will be fabricated and installed on No. 22 CCHX. The new closure head will be designed and fabricated to the same specifications as the modified head on No. 21 CCHX and will include a manway and davit arrangement. The manways are being added to allow cleaning of the turnaround side tubes and tubesheet of No. 21 & 22 CCHX at power, without having to remove the 72 11 diameter (7900 LB) heat exchanger must be performed during a 72 Hr Tech Spec action statement (3/4.7.4 "Service Water System"). The new manways are similar to the manways installed on the existing s.w. inlet/outlet (rear) closure heads of No. 21 &

22 CCHX's which are used for cleaning the S.W. inlet side tubes and tube sheet. The margin of safety of the component cooling heat exchangers is defined, in part, by the requirements imposed by the ASME code. The design requirements for the proposed modification have been satisfied. The function of No. 21 & 22 CCHX's has not changed. Ih addition, the proposed modification is being performed during No. 21 & 22 SW nuclear header maintenance outage as allowed by Technical Specification 3.9.8.2 provided the requirements of the subject Technical

• Specification are satisfied. The margin of safety is, therefore, unaffected. (SORC 94-027) 2EC-3278 Pkg 1 "Pressurizer Upgrades" - A.) Replacement of Pressurizer Spray Bypass Valves: 2PS2 and 2PS4 will be replaced in their current location. The associated manual remote valve operators and their flexible shafts will be permanently removed.

SUMMARY

B.) Replacement of Cables: Power cables 2A3YACA-A and 2B3YAJA-B and control cables 2A3YAC2B-AT and 2B3YAJ2B-BT, in the pressurizer cubicle, for the MOVs of Pressurizer PORV Stop (Block) Valves 2PR6 and 2PR7 will be replaced with high temperature IEEE 323 and 383 qualified.Rockbestos "Firewall SR" cable. Cables 2A3YACA-A and 2B3YAJA-B will be increased in size from 3/C #12 to 3/C #8 to improve voltage regulation. C.) Replacement and Relocation of E/P Transducers for Pressurizer Spray Valves:

Transducers 2PS1-CONV and 2PS3-CONV for pressurizer spray valves 2PS1 and 2PS3, respectively, will be replaced, retagged 2IP5739 and 2IP5741 and will be relocated to a new panel outside the pressurizer cubicle. Existing cables to the transducers will be pulled back and rerouted to the new panel. Control air supply tubing will be rerouted-from the vicinity.

of the valves to the new panel located outside the pressurizer cubicle. Pneumatic air signal tubing will be routed from the E/Ps in the new panel to the positioners on the valves. Existing valves on the control air supply headers to the 2PS1 and 2PS3 valves will be tagged 2CA1964 and 2CA1965 respectively. The pressurizer spray valves, the pressurizer spray valve transducers and the pressurizer spray valve bypass valves are not discussed in any of the Technical Specifications or their design bases. Technical Specification 3/4.4.5 requires two PORVs and their block valves to be operable in Modes 1, 2 and 3. The replacement of the EQ power and control cables to the PORV block valves 2PR6 and 2PR7 will be implemented during Mode 5 with the RCS drained and vented. Therefore, this modification will not reduce the margin of safety as defined in the basis for any Technical Specification. (SORC 94-027) 2EC-3179 Pkg 5 "Salem Fire Damper Upgrade" - The design scope for this package includes the replacement & relocation of existing fire dampers in the Unit 2 switchgear &

fire barrier. New duct sections will be installed in these dampers' present locations. Fire damper 2CVF-815 is a new 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> damper that will be located in an existing sleeve in the fire barrier.

Penetration seal activities required to support this modification involves breaching and resealing a penetration to route temporary power and lighting and the breaching and repair of the penetration seal to facilitate cable removal. The basis for the Technical Specifications does not address either the fire protection features or the SPAV system. The replaced or new fire dampers associated the SPAV system perform no safety related functions. Since the area temperatures are suitable for the safety related equipment located in the area served by the SPAV system, the equipment is available during this modification. There is no reduction in the margin of safety as defined in the basis for any Technical Specification. (SORC 94-036) 2EC-3179 Pkg 7 "Salem Fire Damper Upgrade" - The design scope for this package Unit 2 includes the addition of a new fire damper and modification of an existing fire damper in the Control Area Air Conditioning System (CAACS). The function, basic configuration and

• operation of the system will not be altered and the codes, standards, qualification and design criteria of the original system will apply. Fire damper 2CAF-202 will be modified to obtain a 1.5 hour5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> rating. Damper 2CAF-203 presently functions as a fire damper & also as a gas control damper interconnected to the Halon 1301 Fire Extinguishing System for the Relay Room. Its fire damper function will be replaced with a ne 1.5 hour5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> rated fire damper 2CAF-208 and will be located within the fire barrier. Damper 2CAF-203 will remain as the gas control damper required for the Halon 1301 Fire Extinguishing System; if necessary, this damper will be removed temporarily for access during installation and later returned to its existing

location. Fire damper 2CAF-202 and the ductwork between it and the fire barrier will be wrapped with a fire wrap for a 1.5 hour5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> fire rating. Fire damper 2CAF-208, which is located in the fire barrier, will not require fire wrap. Existing fire wrap on damper 2CAF-203 is no longer required and will be removed.

The basis for the Technical Specifications does not address the fire protection features. The Technical Specifications discuss the surveillance requirements for the Control Room Emergency Air Conditioning System (EACS) . Since replaced or modified fire dampers associated with the CAAC system perform no safety related functions; these modifications do not affect the safety related system which is required for safe shutdown. There is no reduction in the margin of safety as.defined in the basis for any Technical Specification. (SORC 94-036)

B. Procedures and Revisions S2.0P-SO.CC-0002(Q) 11 21 & 22 Component Cooling Heat Exchanger Operations" - These changes will limit th~ total service water flow if the Service Water (SW) system is challenged by an accident scenario that coincides with a single active component failure of the CCHX flow or temperature control devices. These are temporary restrictions which will be in place only up to a river temperature of 10° Fahrenheit. DCPs lEC-3316 and 2EC-3274 will be installed prior to the river temperature reaching 10°. These two DCPs will address the excess flow through the CCHXs resulting from a flow control device failure, by means of a fixed restriction (manual valve permanently throttled) . Engineering Calculation S-C-SW-MDC-1347 demonstrates that with these operating procedure revisions, the CCHX will satisfy normal plant operating conditions for the rejection of heat and will also perform the required design function for heat rejection from the Component Cooling System during the most limiting accident scenario.

• This proposal will result in no reduction in SWS flow to the CCHXs. This flow reduction does not reduce the capability of the CCHXs to perform

• SALEM GENERATING STATION MONTHLY OPERATING

SUMMARY

- UNIT 2 APRIL 1994 SALEM UNIT NO. 2 Reactor power varied during the period as a precautionary measure due to the continuous challenges of heavy grass at the circulator inlet area. Reactor power was gradually increased from approximately 40% to approximately 80% over the period from April 11-29, 1994, as river grass conditions improved. On April 29, 1994, power was reduced to approximately 25% for repairs to a reactor coolant system flow transmitter. The Unit continued operating at reduced power throughout the remainder of the period as repairs were performed.
